This technical guidance is directed at pool contractors, architects, educators, and program staff at relevant agencies, authorities having jurisdiction, and community choice energy programs. This guide is most appropriate for the single-family or smaller multifamily residential poolmarket, and touches on equipment sized for larger pools only briefly.
This guide includes the results of interviews with four Bay Area swimming pool contractors who install heat pumps, including the products they sell and best practices for designing with heat pump pool heaters. This guide draws from product documentation to identify the best products for Bay Area climates.
While common world-wide and regionally in the U.S. (e.g. Florida, Hawaii), heat pump pool heaters are a growing market in the Bay Area due to the ~1% adoption of all-electric new construction in California from 2010-2019, according to SCE’s internal review of building permits. As of spring of 2021, many Bay Area cities have adopted prohibitions or Code-based discouragements on installing natural gas infrastructure, making it necessary to provide technical assistance to designers who are supporting new construction of swimming pools.
